BALLI-01 clinical trial evaluating lasme-cel in r/r B-ALL – Oral Presentation

The BALLI-01 final Phase 1 data will be presented as an oral presentation by Nitin Jain, M.D., Professor of Medicine, Department of Leukemia at the University of Texas MD Anderson Cancer Center in Houston, TX.

45 patients in third line and beyond (3L+) were treated in the BALLI-01 study. 15 patients were treated at the recommended Phase 2 dose and 7 in the target Phase 2 population. Patients were heavily pretreated with those in the target Phase 2 population receiving a median of 5 prior lines of therapy (Range 2-11). Almost all patients were previously treated with blinatumumab (82%) and were also heavily exposed to CD19 CAR-T (53%), CD22-directed antibody-drug conjugate (ADC) (56%) and many had a prior hematopoietic stem cell transplantation (HSCT) (47%).

Final Phase 1 data

In the target Phase 2 population

An overall response rate (ORR) of 100% (7/7) was achieved with a complete remission/complete remission with incomplete count recovery (CR/CRi) rate of 57% (4/7). Of these, 75% achieved minimal residual disease negative (MRD-ve) status.

All patients subsequently proceeded to HSCT.

Lasme-cel demonstrated a manageable safety profile

Cytokine release syndrome (CRS) ≥ grade 3 occurred in 4% of patients.
Immune effector cell-associated neurotoxicity syndrome (ICANS) ≥ grade 3 occurred in 4% of patients.
Immune effector cell-associated hemophagocytic lymphohistiocytosis-like syndrome (IEC-HS) ≥ grade 3 occurred in 2% of patients.
All CRS, ICANS, and IEC-HS resolved.

"These final Phase 1 results are particularly meaningful for a patient population that has very limited treatment options" said Nitin Jain, M.D., Professor of Medicine, Department of Leukemia at UT MD Anderson. "Being able to achieve deep remissions in these patients and allowing them to subsequently receive an HSCT is promising. We look forward to accelerating accrual into the ongoing Pivotal Phase 2 study and bringing this treatment to patients."

The Pivotal Phase 2 BALLI-01 trial is open for recruitment. Eligible patients and treating physicians are encouraged to visit BALLI-01 (NCT04150497) or contact Cellectis at [email protected] for information and participating sites. The first interim analysis is expected in Q4 2026.

NATHALI-01 clinical trial evaluating eti-cel in r/r B-NHL – Poster Presentation

The NATHALI-01 preliminary data on the role of alemtuzumab in optimizing responses will be presented as a poster by Professor Emmanuel Bachy, M.D., Ph.D., Department of Hematology, Hospices Civils de Lyon, France.

Eti-cel is a highly differentiated product being the first allogeneic dual CAR-T targeting both CD20 and CD22, for patients with r/r B-NHL.

As of the February 2026 data cutoff, 14 patients with r/r B-NHL had been treated across three dose levels, in a heavily pre-treated population with a median of 3 prior lines of therapy, 93% of whom had received prior CD19-directed CAR-T therapy, and all of whom presented with stage IV disease at baseline.

In the optimal dose cohort, ORR and complete response (CR) were 88% and 63%, respectively. The analysis identified a positive correlation between alemtuzumab exposure and clinical outcomes: higher alemtuzumab exposure created a favorable lower inflammatory homeostatic milieu prior to eti-cel infusion and was associated with enhanced eti-cel expansion and higher response rates. Additionally, responders maintained sustained low-level interleukin 2 (IL-2) secretion when compared to non-responders.

These findings provide a scientific rationale for the implementation of a weight-based alemtuzumab dosing regimen, currently under investigation to optimize lymphodepletion. Additionally, subcutaneous low-dose IL-2 is being investigated to further enhance eti-cel expansion and treatment response.

"These encouraging data demonstrate that not only can eti-cel drive responses in a very difficult-to-treat population, but that by optimizing exposure to alemtuzumab we may be able to create a favorable environment for CAR-T expansion and persistence." said Professor Emmanuel Bachy, M.D., Ph.D., Department of Hematology, Hospices Civils de Lyon, France.

The NATHALI-01 study is open for recruitment with the full Phase 1 clinical data expected in Q4 2026.

"Despite recent advances in CML treatment, there remains a need for highly effective therapies with excellent safety and tolerability profiles optimized for long-term treatment and capable of deep and durable molecular responses," said Dennis Kim, M.D., Professor of Medicine in the Department of Medical Oncology and Hematology at the Princess Margaret Cancer Centre, Canada. "The updated data from the ENABLE trial are very promising and encouraging. The trial demonstrated meaningful responses across lines of therapy in heavily pretreated patients, including responses in patients who had shown a lack of efficacy to the most effective approved therapies. Further, ELVN-001 demonstrated a favorable safety and tolerability profile, reflecting its high selectivity. I look forward to the initiation of the planned Phase 3 ENABLE-2 trial, which could establish ELVN-001 as an important new treatment option for patients with previously treated CML."

"These promising results continue to showcase the consistency of ELVN-001’s overall profile and reinforce its potential to be a best-in-class ATP-competitive inhibitor with differentiated activity relative to allosteric inhibitors," said Helen Collins, M.D., Chief Medical Officer of Enliven. "In these data, we observed higher response rates in patients treated in earlier lines of therapy, and comparable response rates regardless of prior asciminib exposure. We are also thrilled by the outcome of our recent End-of-Phase 1 meeting with the FDA, where we reached alignment on the 80 mg once daily dose and the inclusion of patients who have received at least one prior TKI in the planned ENABLE-2 Phase 3 trial. This is an important milestone as we advance towards initiating ENABLE-2 later this year."

ELVN-001 is a potent, highly selective, potentially best-in-class small molecule kinase inhibitor designed to specifically target the BCR::ABL1 gene fusion, the oncogenic driver for patients living with CML. Data presented at EHA (Free EHA Whitepaper) are from the ongoing ENABLE Phase 1 clinical trial, which enrolled patients with CML that is relapsed, refractory or intolerant to available tyrosine kinase inhibitors (TKIs) (NCT05304377).

ELVN-001 Updated Data Highlights

ENABLE Has Enrolled a Heavily Pretreated Patient Population

As of the cutoff date of March 10, 2026, 161 patients were enrolled in the ongoing Phase 1 trial across dose levels ranging from 10-240 mg daily.
Most patients (76%) remain on study with a median treatment duration of 35 weeks.
Patients enrolled were heavily pretreated, with 70% having received three or more prior unique TKIs and 23% having received five or more unique TKIs.
62% of patients received prior asciminib, and these patients were more heavily pretreated than the overall trial population: 93% received three or more prior unique TKIs, and 34% received five or more unique TKIs.
8% of patients enrolled with mutations associated with resistance to allosteric inhibitors, increasing from 4% in Phase 1a to 11% in Phase 1b.
Encouraging ELVN-001 Efficacy Data by 24 Weeks

Of the 90 patients enrolled in the Phase 1b, 78 had typical BCR::ABL1 transcripts and had at least one post-baseline transcript; 69 patients were evaluable for major molecular response (MMR) by 24 weeks.
Additionally, of the 49 patients enrolled in the 80 mg once daily (QD) Phase 1b cohort, 37 had typical BCR::ABL1 transcripts and had at least one post-baseline transcript; 28 patients were evaluable for MMR by 24 weeks.

Deep Molecular Response (DMR) achievement rates were also encouraging.
By 24 weeks, DMR was achieved in 22% of patients in the overall Phase 1b and 30% of patients in the 80 mg QD Phase 1b cohort.
Response rates were higher in less heavily pretreated patients, and prior asciminib exposure did not meaningfully impact response rates.

ELVN-001’s Safety Profile Consistent with High Selectivity for ABL1

ELVN-001 was generally well-tolerated, consistent with its high selectivity.
6% of patients discontinued due to adverse events.
The majority of treatment-emergent adverse events (TEAEs) were Grade 1 or 2.
Grade ≥3 TEAEs were reported in 53/158 (34%) patients overall; with thrombocytopenia (6%), neutropenia (6%) and lipase elevation (6%) as the most common.
At the biologically optimal dose of 80 mg QD (n=62), Grade ≥3 TEAEs were reported in 15/62 (24%) patients, with thrombocytopenia (6%) being the only Grade ≥3 TEAE reported in >5% of patients.
Key Outcomes from the End-of-Phase 1 Meeting with the FDA

80 mg QD selected as the recommended dose for Phase 3 ENABLE-2 trial.
ENABLE-2 is expected to enroll patients with CML previously treated with one or more TKIs, and to be randomized to receive either ELVN-001 or physician’s choice of an ATP-competitive TKI.
Additional details of the Phase 3 trial design are expected to be finalized following further discussions with the FDA, including at a planned End-of-Phase 2 meeting anticipated in the third quarter of 2026.
The oral presentation titled: "ENABLE: Updated Efficacy and Safety Results of ELVN-001, a Novel Selective ATP-Competitive Inhibitor of BCR::ABL1, in Patients with Previously Treated CP-CML" will be presented today at 5:45 p.m. CEST during the European Hematology Association (EHA) (Free EHA Whitepaper) Congress in Stockholm, Sweden, by Dennis Kim, M.D., Professor of Medicine, Department of Medical Oncology and Hematology at the Princess Margaret Cancer Centre, Canada.

About the ENABLE Trial
The ENABLE study (NCT05304377) is a Phase 1 study of ELVN-001 in patients with previously treated CML. ENABLE is a dose escalation and expansion trial designed to evaluate safety and tolerability and to determine the recommended dose for further clinical evaluation of ELVN-001 in patients with CML with and without T315I mutations that is relapsed, refractory or intolerant to TKIs. Secondary endpoints include pharmacokinetics, MMR by central quantitative reverse transcriptase polymerase chain reaction, duration of MMR, BCR::ABL1 transcript levels and complete hematologic response.

About ELVN-001
ELVN-001 is a potent, highly selective, potentially best-in-class small molecule kinase inhibitor designed to specifically target the BCR::ABL gene fusion, the oncogenic driver for patients with chronic myeloid leukemia. ELVN-001, a highly selective active-site TKI, has a mechanism of action that is complementary to allosteric BCR::ABL1 inhibitors, which may play an increasingly important role in the standard of care. ELVN-001 was designed to have activity against the T315I mutation, the most common BCR::ABL1 mutation, which confers resistance to nearly all approved TKIs, as well as activity against mutations known to confer resistance to allosteric BCR::ABL1 inhibitors.

FDA grants Priority Review for Roche’s Tecentriq for a certain type of stage III colon cancer

On June 11, 2026 Roche (SIX: RO, ROP; OTCQX: RHHBY) reported that the U.S. Food and Drug Administration (FDA) has accepted the company’s supplemental Biologics License Application (sBLA) filing for adjuvant Tecentriq (atezolizumab) and Tecentriq Hybreza (atezolizumab and hyaluronidase-tqjs) in combination with chemotherapy in stage III deficient DNA mismatch repair (dMMR) or microsatellite instability-high (MSI-H) colon cancer, a type of tumour characterised by high mutation rates. The FDA has granted Priority Review and is expected to make a decision on the approval by 9 October 2026.

"This filing acceptance brings us closer to establishing adjuvant Tecentriq plus chemotherapy as a new standard of care for certain types of early colon cancer," said Levi Garraway, MD, PhD, Roche’s Chief Medical Officer and Head of Global Product Development. "The ATOMIC results demonstrate that Tecentriq plus chemotherapy can substantially reduce the risk of disease recurrence or death, helping more patients remain cancer-free following surgery."

"One in three patients with stage III colon cancer will relapse within five years, underscoring the need for new adjuvant treatment options," said Michael Sapienza, CEO, Colorectal Cancer Alliance. "This milestone represents a critical step toward a reality where treatment is tailored to a patient’s specific tumor biology from the very beginning, giving them a better chance of preventing a recurrence."

The application is based on the landmark ATOMIC study, recently published in The New England Journal of Medicine. ATOMIC demonstrated that adding Tecentriq to standard FOLFOX6 chemotherapy reduced the risk of disease recurrence or death by 50%, compared to chemotherapy alone for people with stage III dMMR colon cancer, determined by an immunohistochemistry test, such as the VENTANA MMR RxDx Panel. The 36-month disease-free survival was 86% for Tecentriq combined with FOLFOX6 compared with 76% in the FOLFOX6 alone group. The safety profile was consistent with previous studies of Tecentriq and FOLFOX6.1

Colon cancer remains one of the world’s most common and deadliest tumours.4 Over one million people are diagnosed globally each year, and despite surgery and chemotherapy, approximately 30% of stage III patients relapse within five years.2-4 Approximately 15% of colon cancer patients present with dMMR/MSI-H tumours, which indicate a higher mutation rate and thus have the potential to respond to immunotherapy.5

Roche is pursuing further regulatory filings for Tecentriq, including with the European Medicines Agency, to bring this first immunotherapy-based adjuvant option to patients with dMMR/MSI-H colon cancer worldwide.

The ATOMIC study was sponsored by the National Cancer Institute (NCI) and conducted by the Alliance for Clinical Trials in Oncology in partnership with Roche and the Arbeitsgemeinschaft Internistische Onkologie (AIO) group in Germany. It highlights Roche’s commitment to working alongside leading academic groups to tackle some of the most challenging cancers.

About the ATOMIC study
ATOMIC (A021502, NCT02912559) is a phase III, randomised, open-label, multicentre study investigating the addition of Tecentriq (atezolizumab) to FOLFOX6 chemotherapy (a combination of folinic acid, fluorouracil, and oxaliplatin) in patients with stage III colon cancer who have a deficiency in DNA mismatch repair (dMMR). The trial enrolled 712 patients. Participants were randomised 1:1 to receive either FOLFOX6 plus Tecentriq for 12 cycles (six months) followed by Tecentriq monotherapy for 13 cycles (an additional six months), or FOLFOX6 alone for 12 cycles. The primary endpoint is disease-free survival (DFS).

About Tecentriq (atezolizumab)
Tecentriq is a monoclonal antibody designed to bind with a protein called PD-L1, which is expressed on tumour cells and tumour-infiltrating immune cells, blocking its interactions with both PD-1 and B7.1 receptors. By inhibiting PD-L1, Tecentriq may enable the re-activation of T cells. Tecentriq may also affect normal cells.

Tecentriq has been approved for some of the most aggressive and difficult-to-treat forms of cancer, and is the first PD-(L)1 cancer immunotherapy available in both subcutaneous and intravenous formulations.

Nurix Therapeutics to Report Updated Phase 1a/b Results for BTK Degrader Bexobrutideg, Highlighting Durable Responses in Relapsed/Refractory CLL/SLL and Promising Activity in Earlier Lines of Therapy

On June 11, 2026 Nurix Therapeutics, Inc. (Nasdaq: NRIX), a clinical-stage biopharmaceutical company focused on the discovery, development and commercialization of targeted protein degradation medicines, reported updated clinical data from the Company’s ongoing NX-5948-301 Phase 1a/b clinical trial evaluating bexobrutideg (NX-5948), an investigational oral CNS-penetrant BTK degrader, in patients with chronic lymphocytic leukemia (CLL). The data will be presented during an oral presentation at the 2026 EHA (Free EHA Whitepaper) Congress taking place June 11–14, 2026, in Stockholm, Sweden.

"These updated data continue to demonstrate the differentiated profile of bexobrutideg, including durable responses in heavily pretreated patients and encouraging activity in patients earlier in their treatment journey," said Talha Munir, M.B. Ch.B., Ph.D., consultant hematologist at Leeds Teaching Hospitals NHS Trust and deputy chair of the United Kingdom National Cancer Research Institute CLL Study Group. "Importantly, responses were observed across patients with difficult-to-treat disease characteristics, including BTK inhibitor resistance mutations, high-risk molecular features and CNS involvement, while maintaining a favorable tolerability profile."

"With longer follow-up in relapsed/refractory CLL and expansion into earlier-line treatment settings, we continue to see a consistent efficacy and safety profile for bexobrutideg," said Paula O’Connor, M.D., chief medical officer of Nurix. "The durability of responses observed in heavily pretreated patients together with the promising activity seen in BCL2i-naïve and BTKi-naïve patients further support the broad potential of BTK degradation across all lines of therapy in CLL."

"These latest findings continue to reinforce our belief that bexobrutideg has the potential to redefine BTK-directed therapy and emerge as a potentially best-in-class treatment for CLL," said Arthur T. Sands, M.D., Ph.D., president and chief executive officer of Nurix Therapeutics. "The updated data to be presented at EHA (Free EHA Whitepaper) across Phase 1 cohorts continue to support the launch of a broad Phase 3 monotherapy program and strengthen the rationale for exploring the use of combination regimens in first- and second-line patients. We look forward to advancing these programs through our recently announced collaboration with Roche."

Growing Safety Cohort Continues to Support Differentiated Profile
Across all Phase 1a/b CLL patients (n=142), bexobrutideg was well tolerated, consistent with prior disclosures, with safety findings generally comparable between patients treated at the 600 mg RP2D and the broader study population.

As of the January 1, 2026, data cutoff:
•No dose-limiting toxicities were observed
•No treatment-related Grade 5 adverse events were reported
•Treatment discontinuations due to adverse events occurred in only 5.6% of patients
•The most common treatment-emergent adverse events included purpura/contusion, neutropenia, petechiae, diarrhea, and fatigue.

Updated Phase 1a Data in Relapsed/Refractory CLL Continue to Support Durable Responses
The Phase 1a dose escalation study enrolled 48 patients with relapsed/refractory CLL/SLL treated with bexobrutideg at doses ranging from 50 mg to 600 mg once daily. Patients were heavily pretreated, having received a median of four prior lines of therapy (range 2–12), including prior BTK inhibitors (97.9%), prior BCL2 inhibitors (83.3%), and prior non-covalent BTK inhibitors (27.1%). Baseline high-risk features included BTK inhibitor resistance mutations (38.3%), TP53 mutations (44.7%), PLCG2 mutations (14.9%), and central nervous system (CNS) involvement (10.4%).

As of the January 1, 2026, data cutoff:
•Median follow-up was 22.4 months
•Median progression-free survival (PFS) was 22.1 months (95% CI: 14.0–NR)
•Objective response rate (ORR) was 83.0% (95% CI: 69.2–92.4)
•Responses included two complete responses, one nodal partial response, and 36 partial responses.
•Responses were observed across patients with BTK inhibitor resistance mutations, high-risk molecular features, and CNS involvement

Phase 1b Data Supports High ORR in Earlier-Line Cohorts
Nurix also presented new data from two of the Phase 1b cohorts evaluating bexobrutideg in earlier lines of treatment, including patients who had received prior BTKi treatment but were BCL2i-naïve (Cohort 5) and patients who were BTKi-naïve, including treatment-naïve patients (Cohort 15).

In Cohort 5 (n=19), patients had received prior BTK inhibitor therapy but no prior BCL2 inhibitor:
•ORR was 92.9% (95% CI: 66.1–99.8) among evaluable patients (n=14)
•18 of 19 patients remained on treatment at data cutoff
•Median follow-up was 5.2 months
•Five patients have not yet reached their first scan but remain on treatment

In Cohort 15 (n=20), which included BTKi-naïve and treatment-naïve patients:
•ORR was 84.2% (95% CI: 60.4–96.6) among evaluable patients (n=19)
•19 of 20 patients remained on treatment at data cutoff
•Median follow-up was 4.9 months
•Three patients with stable disease remain on treatment

About Bexobrutideg
Bexobrutideg (NX-5948) is an investigational, orally bioavailable, brain-penetrant, highly selective small-molecule degrader of Bruton’s tyrosine kinase (BTK) being developed by Nurix and Roche as a potential best-in-class therapy across oncology, immunology and neurology.
